Product details
Overview
74HCT02PW,118 from Nexperia is a quad 2-input NOR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 14-pin TSSOP package (SOT402-1), -40 °C to +125 °C operating range, and 11 ns typical propagation delay at 4.5 V supply. It serves as a discrete combinational logic building block in digital control, interface translation, and enable/disable signal conditioning circuits.
For engineers reviewing the 74HCT02PW,118 datasheet, 74HCT02PW,118 pinout, 74HCT02PW,118 application, or 74HCT02PW,118 equivalent, this device is selected for robust noise immunity (2.0 V VIH / 0.8 V VIL), low-power CMOS operation (ICC < 40 μA at 5.5 V), and compatibility with legacy 5 V TTL systems while driving standard CMOS loads.
Technical Context
The 74HCT02PW,118 implements four independent 2-input NOR gates using silicon-gate CMOS technology. Each gate features input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
Its TTL-level inputs accept standard 5 V logic thresholds, while outputs swing rail-to-rail (VOH ≥ 3.7 V, VOL ≤ 0.4 V at IO = ±4 mA) and drive up to ±4 mA loads. The device operates across 4.5–5.5 V and is specified for industrial and extended temperature ranges.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT02D,653 | SO14 package (SOT108-1); 3.9 mm body width; 1.27 mm lead pitch; higher thermal resistance (10.1 mW/K derating above 100 °C) | Better suited for through-hole prototyping or legacy PCBs with SOIC footprints; less dense layout than TSSOP | Select when board space permits larger footprint or reflow compatibility with SOIC-14 stencils is required |
| SN74HCT02DR | Texas Instruments part; identical logic function and DC specs; slightly longer tpd (13 ns typ at 5 V); different ESD ratings (HBM 4000 V) | Approved for use in TI-design reference schematics; broader qualification documentation for automotive-adjacent designs | Choose when TI ecosystem alignment or higher HBM ESD margin is prioritized over Nexperia's tighter 11 ns delay |
Compared with 74HCT02D,653, the 74HCT02PW,118 offers 35 % smaller board area and improved thermal performance in high-density layouts; versus SN74HCT02DR, it delivers faster propagation and lower dynamic power (CPD = 22 pF vs 25 pF), making it preferable for timing-critical or battery-sensitive applications.

FAQ
Can 74HCT02PW,118 operate reliably at 3.3 V supply?
No - the 74HCT02PW,118 is specified only for 4.5 V to 5.5 V operation. Its TTL input thresholds (VIH ≥ 2.0 V) require minimum VCC = 4.5 V to guarantee proper recognition of HIGH inputs; at 3.3 V, VIH exceeds 60 % of VCC, violating JEDEC JESD8C compliance and risking logic misinterpretation.
What is the maximum capacitive load this device can drive without timing degradation?
The 74HCT02PW,118 is characterized with CL = 50 pF in its dynamic specifications. Driving loads beyond 50 pF increases propagation delay nonlinearly - e.g., at 100 pF, tpd rises ~35 % over nominal. For stable timing, keep total load (including trace capacitance and input CI ≈ 3.5 pF) below 50 pF or add a buffer stage.
Does the exposed pad on the TSSOP14 package require soldering or grounding?
No - the TSSOP14 (SOT402-1) package for 74HCT02PW,118 has no exposed thermal pad. Unlike QFN variants (e.g., SOT762-1), its construction uses standard gull-wing leads only; thermal dissipation relies on copper pour under the body and lead conduction, not pad attachment.
How does input clamping affect interfacing with 12 V sensors?
Clamp diodes allow safe connection to 12 V signals when a series current-limiting resistor ≥ 560 Ω is used - limiting IIK to ≤ ±20 mA per input. This enables direct interface to industrial 12 V proximity switches without external protection, provided resistor power rating exceeds 200 mW peak.
